Of Producers and Parasites

I found this chart reading an article about the flat tax, and while it's original purpose was to demonstrate that even under a flat tax New Zealand's rich would still be paying the lion's share of the taxes, I noticed that the poor got one heck of a deal (either way) in that they contributed nowhere near the amount of resources they consumed.



Would be curious if anybody has/knows of similar data for the US or other OECD countries.
